Consider "Britain BC" and "Britain AD" by Francis Pryor for a start. One thing that the recent (since I was in university in the '60s) archaeology has taught us (yet again) is that no one writes history without having an angle (no pun) and the angle is often political with the result that history is very often quite misleading if not outright wrong. The notion throughout European history and archaeology that changes in physical culture (tools, pots, etc.) and even language necessarily mean wholesale changes in populations is being seriously called into question by recent archaeology and DNA studies.
